Serial No. 655,83e.

To all whom it may cancer n:

Be it known that I, EUGENE C. RICKER, a citizen of the United States,and a resident oi' Scranton, in the county of Lackawanna and State ot'Pennsylvania, have invented a new and Improved Alarm, of which thefollowing is a full, clear, and exactdescription.

My invention relates generally to alarms and more particularly to adevice adapted to be positioned on a door casing and actuated by openingof the door.

The object of my inventon is to provide an alarm device of simpleConstruction which is adapted to be used on either side of a door casingwith doors opening in either direction, the Construction and arrangenentbeing such that an etlicient device of low cost of manufacture isproduced.

A further object of the invention is to provide in a certain structurean alarm device which will give warning whenever an attempt is made toopen a particular door, thereby either frightening away an intruder ormaking his capture easy.

A further object of my invention is to provide a thief or burglar alarmwhich gives warning through the explosion of a Cartridge or otherexplosive constructed and arranged to be set or engaged from either sideof a door or opening and particularly adapted to engage with the bolt ofa rim lock and released by a push or pull from either side of the saidlock or other suitable connection.

A further object of my `invention is to provide a thief or burglar alarmmade up of a firing pin which, through its movement, explodes a suitableCartridge or other explosive, the pin being held in operative positionand released therefrom by movement of a door in either direction, therebeing a spring in engagement with the pin whereby it is brought intoengagement with the cartridge.-

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is apartial side View of a door and a casing showing my clevice in operativeposition; Fig. 2 is a vertical sectional view thereof on the line 2-2 ofFig. l; Fig. 3 is .a side view of a modifiedform of bolt Fig.

4. is a transverse sectional view showing the liring pin in the positionit occupies when the device is applied to the door casing atright-angles to the (loor casing.

The device is adapted to be positioned on a casing l adjacent a door 2,the door being provided with any suitable bolt 3. The device itself ismade up of a base 4 having a firing pin 5 positioned thereon by anysuitable neans, such as guides G, 7.

Referring particularly to Fig. 2 it is to be noted that one end 8 of thepin is ofl'set while the other end 9 is tapered, there being shoulders10 on opposite sides of the pin and adjacent the said tapered end.Surrounding the pin between the guides (i, 7, is a helical spring 11,one end of which preferably rests against the guide 7 While the otherend bears against the stop 12 carried by the firing pin. The base %i isalso provided with a suitable guide or holding device 13 adapted toreceive and nold a cartridge l-l, the cap of the Cartridge being in linewith the tapered end of the pin 5 when it is released 't'i-oni theposition shown in Fig. 2.

As shown in F igs. l and 2 the device is positioned on the inside of thecasing 1, the door 2 swinging toward the observer, the bolt &when thedoor is swung,engaging the offset end 8 ol? the tii-ing pin, therebycarrying the shoulder 10 out of engagement with the guide 6 andpermitting the spring 11 to bring the tapered end 9 of the firing pininto engagement with the cap on the Cartridge, thereby exploding thesame. By making the firing pin 'reely rotatable within the guides (i, 7,and by providing the shoulder-s 10 at opposite sides thereof I haveproduced a device which may be used in the position shown in Figs. l and2 as in the position shown in Fig. 4:. lVhen the device is used as shownin Fig. 4, it is ati tached to the door casing at right angles theretoand the firing pin 5 is turned 180 from thatshown in Fig. 2, so that theshoulder 10 at the opposite side of the pin engages the guide G and theofl'set end 8 thereof extends in front of the door. Now when the door isopened, it engages the otset portion 8, moving it and bringing theshoulder 10 out of engagement with the guide 6 and permitting thetapered end of the pin to come into engagement with the Cartridge,

' form of pin in the position shown in Fig. 2

by engagement of the notch with the lower guide 7 release of theengagement actuating the device as previously described. In either casethe bolt 3 releases the firing pin, the tapered end thereof coming intoengagement with the Cartridge by means of the spring, and exploding it.Such an alarm is particularly adapted for use in poultry houses whereany attemptto enter gives warning to the neighborhood; the parts of thedevice are few and when once set in operative position require nofurther attention so that it is not necessary each time the house orroom is closed to try the alarm. Of course any form of bolt 3 can beused, the bolt being movable out of the path of the offset end of thefiring pin by any suitable means, such as a wire or cord, or by alocking means, as shown in Fig. 1; in the absence of a lock a connectionmay be made with a bolt, which connection extends through the door,thereby enabling it to be set from outside the door.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:
